This section describes the mainframe emulation utilities. You can invoke these utilities in a JCL jobstream or REXX exec by using the same program names, data sets and commands as on the mainframe. The mainframe utilities emulated by MSS are:
- DFSORT and SORT, to perform sort/merge operations
- DSNTEP2, to execute any SQL statement that can be executed dynamically
- IDCAMS, to manage VSAM data sets
- IEBCOMPR, to compare two sequential or partitioned data sets
- IEBCOPY, to copy or merge partitioned data sets
- IEBGENER, to copy sequential data sets
- ICEGENER, like IEBGENER but with VSAM capabilities
- IEBUPDTE, to create or modify sequential or partitioned data sets
- IEFBR14, to provide a dummy program facility by simply returning to the caller
- IKJEFT01, to submit TSO commands in batch mode (also IKJEFT1A and IKJEFT1B)
- IRXJCL, to run a REXX exec in MVS batch mode
- IEBDG, to create test data
These names are defined as aliases for the equivalent MSS utility.
This section describes the special considerations that apply when you use these utilities in a MSS environment. It does not include information on behavior that is the same in mainframe and MSS environments. For full information on the mainframe utilities referred to in this section, see the relevant IBM documentation.
Note:
If you wish to debug programs invoked by IKJEFT01, you must specify its equivalent MSS utility, IDAEFT01, as the program to debug.
